When I turn on the laptop initially, it boots up but all the toshiba functions such as standby, fn key, brightness dont work. When I restart or shutdown, the laptop is frozen at the toshiba screen. I cannot get past the toshiba screen, but will work again after 15 minutes if I leave it off. So if I start from dead, it works fine but no toshiba functions, but if I shutdown or restart, I have to wait 15 minutes before I can get past the toshiba screen and boot into windows. could this be a thermal issue? Is there anyway that the bios chip overheats, is corrupt? Here are my specs.
